Outbound Key Bridge reopens

4:30 p.m.: Police have cleared the intersection and traffic is flowing in both directions.
4 p.m. Update: Well, that was short-lived. There were some cars allowed earlier, but now traffic seems to be restricted to salt trucks.

3:55 p.m. Update: Outbound traffic is now being allowed onto the bridge.

3:46 p.m. Update: Now there's just once police car blocking the lanes.

3:36 p.m. Update: A second police car has joined the first to block the outbound lanes of the bridge. Earlier, we saw a police officer stop some drivers who were trying to go around.

3:21 p.m. Update: This may take while. There are flares now set up in the intersection to alert motorists to the closure. It's also snowing and visibility is decreasing.

3:12 p.m. Update: Traffic cameras show that a police vehicle is blocking access to the outbound lanes of the Key Bridge. Inbound traffic is flowing normally.
Original post: DDOTDC just tweeted that the outbound Key Bridge is closed for snow removal. No word yet on how long this may take.
